Title: Horizontal synchronizing signal processing circuit
Inventor: BEPPU TAKEYOSHI
IPC: H04N5/12
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To reduce the mixing period of a macro vision signal becoming a noise by forcedly switching a horizontal AFC (PLL) circuit, so that it operates to compare phases only in a gate period during the generation period of the macro-vision signal existing in a synchronizing signal. SOLUTION: A horizontal AFC circuit 1 operates synchronously with a horizontal synchronizing signal from the outside and compares phases only in a gate period by a gate control signal. A synchronization detection circuit 5 determines it to be in a synchronous state, when the horizontal synchronizing signal exists in a gate period from the horizontal AFC circuit 1 and causes the horizontal AFC circuit 1 to compare the phases only in the gate period. It determines it to be in an asynchronous state, when the signal does not exist and stops the gate operation of the horizontal AFC circuit 1.  A vertical count down circuit 6 generates a compulsory switch signal which causes the horizontal AFC circuit 1 to forcedly compare the phases only in the gate period, despite of the determined result of the synchronism detection circuit 5 in the generation period of the macro vision signal which exists in the horizontal synchronizing signal.

IPC: H01M2/12
Filed: 1986-01-30
Abstract: In a multicell electric storage battery designed for central gas release, before being released into the open air the battery gases pass through a container positioned on the block casing in which the acid particles and moisture are separated from the gases as a consequence of the gases being repeatedly deflected by a series of walls placed in the path of the gases, which may be perforated if desired, and the dehumidified gases are then passed through a porous flame-protection frit. Flashback of a flame caused by external ignition of the gases is prevented by rapid burn-off of the gases in a flame extinguishing chamber preceding the frit.
